I got started at the age of fourteen experimenting with old electronic parts I got from my father

In the 80's I started building sound system audio amplifiers. I would then test the amplifier with the test instruments to determine how the amplifier was performing. Everything would look normal, but when I played reggae music through the amplifier, it would over heat. The plates of the KT88 would run red, especially when I played a mix from the great King Tubby's that had subsonic drum and bass frequencies as well as razor sharp high frequencies.
